title: Bilateral stress fractures of the femoral neck with no risk factor : a case report.
abstract: BACKGROUND
  Stress fractures of the femoral neck are uncommon. They are caused by either excessive stress or bone fragility.
  
  
  OBJECTIVE
  To report a case of bilateral stress fracture of the femoral neck in a 15-year-old girl without any risk factors
  
  
  METHODS
  We report a case of bilateral stress fracture of the femoral neck in a 15-year-old girl in whom no risk factors were found. One of the fractures was displaced at first diagnosis and was successfully treated by closed reduction and valgus subtrochanteric osteotomy. The other fracture was initially undisplaced but displacement occurred later despite internal fixation with a dynamic hip screw.
  
  
  CONCLUSIONS
  A high index of suspicion of stress fractures of the femoral neck must be kept in mind even without risk factors. Delays in diagnosis and displacement should therefore be avoided.
